GLA700-2 12V DC 700N Compact Linear Actuator


Custom Actuator Options Symbol
Custom options are also available, please contact us for more information

The GLA700-2 model is a small-sized linear actuator with a high build quality and useful load capacity of up to 700N (71kg). The actuator has a no-load running speed of 9.2mm/s and a full-load speed of 6mm/s.

This model is available in five different stroke lengths (travel distances) of 50mm (2"), 100mm (4"), 150mm (6"), 200mm (8") and 300mm (12").

This model replaces our older GLA750 model and offers improvements over the older version, including a more-stylish body construction and higher quality seals (with IP66 enclosure rating).

The GLA700-2 offers the build quality of higher-cost actuators at an affordable price, with a small body size ideal for providing electrical automation in tight spaces. The operating voltage of 12V DC makes it suitable for powering from a standard lead-acid battery, or running from a mains to 12V DC adapter such as our own high-efficiency 8A model.

The shallow lead-angle of this actuator (with a 3.175mm pitch, single-start screw) means that if the actuator is driven into a position it will tend to stay in that position unless power is applied once again, or unless it is subjected to a load larger than the rated load.  

The outer enclosure features O-ring seals under every screw head as well as gaskets at each seam and a sturdy wiper ring about the extending rod. This design adds up to an IP66 enclosure rating, suitable for most external use. Bear in mind that the actuator should not be submerged in water, or exposed to continuous running water. If mounting outdoors it is best to orient the extending rod tilted downwards, so that water tends to run away from the moving seal between rod and body.

Please bear in mind that, with its all-metal spur gear transmission, this actuator model is not intended to be especially low-noise by design. If your design requires low-noise actuators please look at the GLA1500-N or GLA800-N models, or ask us for advice on other alternatives. 


Leads & Connector Options

The actuator comes with a 0.8m PVC insulated lead as standard (grey external sleeve with two internal copper cores, one red and one black) with bare tinned lead ends. An option is provided for a DC (barrel type) power connector to be added (2.1mm internal diameter, 5.5mm external) on a 300mm lead, bringing the total lead length to 1.1m. Allow for one extra working day to process your order if a connector option is added, since these are soldered and insulated to-order.

We are able to supply custom wiring and connectors upon request, please contact us with your requirements if interested.


User Advice

To change the direction of travel simply swap the polarity of the DC power source to the two actuator leads (this may be achieved using hardware such as our rocker switch harness or GLA-CU-X3 remote control unit). By varying the input voltage between 0-12V DC it is possible to control the speed of the actuator. Reducing the voltage will also reduce load capacity (for example at 6V the actuator will have roughly half of the maximum load capacity at 12V).

This actuator is designed primarily for compression loads, it will typically work OK in tension, up to the same rated maximum load, but can be more susceptible to damage from overloading. Shock loads through the mounting points should be avoided.

As with any DC motor the motor may be run at a higher voltage than the nominal 12V DC however operation at higher voltages will invalidate the warranty. Experienced users who wish to extract greater power from the actuator (at their own risk) should abide by a practical operation ceiling of 18V, above which the motor, diodes and limit switches of the actuator would be significantly more likely to fail. Be aware that the current draw will be greater if the actuator is run at above 12V DC and the duty cycle should be reduced to help avoid over-heating.

Ensure that the control hardware and power source are capable of providing sufficient current for the loads you expect the actuator to experience. We cannot be held liable for damage caused to connected hardware due to inappropriate hardware selection. 


CAD models (STEP, IGS, Autodesk Fusion 360) of the actuator are available upon request. Contact us with the size(s) and file formats that you require and we'll attach the files in return.

Operating Characteristics
Motor:12V DC, up to 35W
No Load speed:9.2mm/s
No Load Current:0.8A
Full Load Speed:6mm/s
Maximum load:700N (71kg)
Current for max. load:2.8A
Stall current:5.8A
To protect the actuator you should use overcurrent protection to prevent sustained stalls.
Maximum static load:1200N (122kg) Holding maximum in compression, maximum tension (pulling) load should be 700N
Noise levels:< 52dB under no-load
< 55dB under full-load
If you need an actuator designed for low-noise output please see the GLA800-N, GLA1500-N or GLA4000-S models. 
Maximum duty cycle:25%
This is the maximum proportion of time that the actuator may be in operation for, up to 2minutes continuously during any one stretch. 
Life expectancy:Nominal 40,000 strokes

Please be aware that there may some variation in the operating performance from actuator to actuator, as a rule-of-thumb allow for at least a 5% difference above/below the given values.
This model, as it does not have a built-in encoder, is not suitable for electrical synchronisation. We have other actuator models available that are better to use if your intention is to run two or more actuators with a synchronised output.
